Hypertech3300 Speedometer Calibrator with Color Screen

This did not work right away for me.. got an error pretty much as soon as I plugged it in on my 08 Ram 2500 6.7.. I called tech support with 15 minutes left in their day.. they knew the error and said they would stay late and get an update out within an hour.. They had it out in 30 minutes.. I updated the calibrator made it farther and got another error.. Took two more calls with Hypertech support and they were great.. fixed the errors in their software quickly, got the updates out and my speedometer is 100% accurate.. Hypertech goes the extra mile to make sure it works. I tried the competitors.. you might find my feedback on theirs, which they were happy with "pretty good" accuracy for their calibrator and having crappy support. You want great support and a product that will work for you.. get Hypertech.. BTW.. as a software application consultant, I was not bothered by them having to do software updates, its part of what I see daily but others might be. What I was rather impressed with, was the speed of the process they had to be able to roll production changes out that quickly.. pretty great work

This is an excellant product but do not buy used. These are locked to the first vehicle used on unless user removes calibration & returns vehicle to stock prior to returning product. People are buying these, programming their vehicle, and then returning for refund. These used units get resold and are unusable since they get locked to the VIN of the vehicle. Confirmed with manufacturer. Returns to retailers should be sent back to Hypertech for "clearing". I bought "USED Like New" but found it was locked. Also be aware that for 2013 Ram 2500 6.7 Diesel in California, Hypertech does not support a unit for sale in CA because of emissions standards. Returned for refund.

After speaking with Hypertech Tech Support to ensure the 3300 was the correct programmer for my model vehicle, I found this gem and purchased it. Much to my surprise, it arrived the next day even though expected arrival was one week out when I ordered it (no problem at all). This was great as I just bought the used vehicle and getting maintenance items up to date. Previous owners lifted and increased tire size without programming Speedo. Affects performance and shift points. Programmer online update was quick (5 minutes). Truck programming took 5-10 minutes at the most. It took me a bit to find the tire size input as I believe it was in a “custom” menu of some sorts. Either way, it was simple and quick. I adjusted the idle rpm as well. Nice little tool. Unfortunately, you have to have one for each individual vehicle, VIN assigned.

Worked great. I changed out the gears in my car and in a couple of minutes the speedometer was back on track. No issues whatsoever. Fast shipping. I received it a day early.

Could not use it because they never sent it back to the manufacturer to get it cleaned out so that it can be fresh in order to use with my vin number of my truck. Also amazon would not send me a replacement because it is an electrical item and or something to that effect. A customer service person talked to me like I was Trying to use it and then Return it. I called the manufacturer and this is a common practice for Amazon.To not send them back to them to get them clean before they resell them.

Hypertech 3300 Speedometer Calibrator with Color Screen: non-California.First, I was buying a new product that was not new when it arrived.The plastic inside of it was shredded, and it had obviously been opened and used before.I went to the website and connected it to the Internet and downloaded the new software.I connected it to my vehicle and it did let me adjust my tire size.This is the only item that could be selected or changed in the computer.I have not verified functionality or accuracy of the speedometer, but I assume I will be able to change it to make it more accurate if it is not perfect.

Worked perfect to calibrate the tires size that I put on my 2016 ram rebel and very easy to change back to factory settings

Ford was unable to code my gear and tire change on my 2010 Ford Explorer Limited even though the options were offered on my model Explorer. They recommended using a SCT tuner. I didn't need to change the tuning, just the speedometer for the tire and gear change. I saw the Hypertech on a explorer forum and decided to go with the Hypertech 3300. It worked flawlessly! I pulled the NAV fuse under the dash as instructed than followed the prompt on the tuner. All said and done it was done less than thirty minutes including replacing the fuse. Speedometer is spot on. We are very pleased. Thank you.
